Alpha (original name Alpha AXP) is a 64-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). Alpha was designed to replace 32-bit VAX complex instruction set computers (CISC) and to be a highly competitive RISC processor for Unix workstations and similar markets.

Feb 6, 2020 · The DEC Alpha, released in 1992, seems like an early implementation of a fully 64-bit microprocessor architecture. Its release led to quite a bit of both marketing hype and genuine vendor support in the mid-1990s, which supported the conclusion that Alpha would be a serious challenger to Intel x86, at least in the high-end performance and ...
Dec 7, 2020 · Dec 8, 2020 at 7:55. 1. @slebetman Right, the idea behind Alpha was very much similar to the one behind Itanium: Make the hardware vastly simpler to maximize performance, handle all the tricky bits in software instead. Both were "next-gen CPU architectures", and saidly neither succeeded in conquering the world of computing. – TooTea.
The DEC Alpha, also known as Alpha AXP, is a powerful 64-bit RISC processor developed by Digital Equipment Corporation (DEC) in 1992. It was specifically designed to replace the older 32-bit CISC-based VAX processors.
Four gold-coloured 300 MHz Alpha 21164 microprocessors on a Cray T3E-600 processor board. DEC Alpha 21164 (EV5) die shot. The Alpha 21164, also known by its code name, EV5, is a microprocessor developed and fabricated by Digital Equipment Corporation that implemented the Alpha instruction set architecture (ISA).
DEC Alpha, a 64-bit RISC processor developed by Digital Equipment Corporation designed to replace their 32-bit VAX instruction set. The 21064 was the first Alpha processor introduced as DECchip 21064, code named EV4, in February 1992 [2], released since September 1992.
Definition. The DEC Alpha was an architecture and line of microprocessors created by Digital Equipment Corporation (DEC). These processors, which began shipping in the early 1990s, were among the most innovative and highest performing of their era.
